The early Christian church not only transformed the Roman Empire through the testimony of its love but also through the testimony of its lips. The Book of Acts tells us that on the day Stephen was martyred, a great persecution arose against the church in Jerusalem, and all except the apostles were scattered throughout Judea and Samaria. Those who were scattered preached the Word wherever they went. Therein lies the second secret of growth in the early church: every believer was a witness for Christ. While it is true that not everyone is called to be an evangelist, everyone is called to evangelize. This is why the church must take seriously the task of equipping believers. For the rest of their lives, as God provides opportunities, believers are to be prepared to make disciples. Jesus said, "This is to my Father's glory, that you bear much fruit, showing yourselves to be my disciples" (John 15:8).
